Introduction

Historically, connecting two buildings to allow networking

between two local area networks required the expense

and effort related to running a cable from one building to

another. This may have involved installing an aerial cable

or digging a trench and installing conduit and wiring

between the two buildings, which is time-consuming,

labor-intensive, and costly.

After installation, cable degradation, due to moisture,

corrosion, or alterations in landscaping, can compromise

the network connection between the two buildings.

Repairing and replacing cable runs is also costly, time-

consuming, and labor-intensive.

RadioLAN overcomes these difficult installation issues

with its Campus BridgeLINK™ product line. This exciting

new technology easily connects two buildings, using radio

frequency technology. Because this technology uses

radio frequency to make the connection between the

buildings, cable runs, conduit, trenching, and labor

involved with these activities are no longer required.

RadioLAN allows you to connect two buildings, which are up to one mile apart, using a Campus BridgeLINK™

Processor Unit (CPU), a Companion Radio Module (CRM), and an 8.86” square directional antenna for each

building link. When using the Campus BridgeLINK™ application, you need only install the components at each

building, aim the antennas toward one another, and power the system on. The only requirements for each

building location are Campus BridgeLINK™ system components and access to network cabling and power.

The directional antenna and its cabling is weatherproof, small-profile, and sturdy. Because the directional antenna

allows for a 19° angle of operation, aiming the antennas so they point toward one another is nearly effortless.

Connecting two networks in two locations using the old-fashioned, hard-wired method could take days,

considering the labor intensive effort needed. When using Campus BridgeLINK, the task is simplified. The task of

connecting two networks is reduced to mere hours, without the back-breaking labor related to trenching, laying

conduit and then cleaning up the landscaping mess afterward.

In this section, we will introduce you to the concepts of Campus BridgeLINK™ communication, using a RadioLAN

Wireless Campus BridgeLINK™ system. Here, you will become familiar with the CPU, the CRM, the directional

antenna, and the signal analysis tools.

10BaseT Port Jack

Next to the MDI/MDI-X selector button you will find the 10BaseT port. The 10BaseT port interfaces the CPU to its

local area network. The 10BaseT port is RJ45-compatible, which allows an eight-wire connection to a network

hub or other hard-wired external device.

10BaseT LED Indicators

On the upper left and right corners of the 10BaseT port are green LEDs which indicate transmit and receive status

from the network.

When the CAR LED illuminates, this indicates that the Ethernet carrier is active.

When the ACT LED illuminates, this indicates Ethernet activity on the network. This LED flickers during normal

operation.

Local Port Jack

Located on the opposite end from the selector button, on the same face of the CPU, is the local port jack. The

local port is compatible with RJ11 connectors and allows connection to a local terminal. When you need a local

terminal connection, use the local terminal to configure the CPU.

A Typical Campus BridgeLINK™ Application

Figure 8 shows a typical Campus

BridgeLINK application in which two

buildings, with local area networks in

each, are located up to one mile away

from one another. Notice that there are

no solid obstructions between the two

buildings and that each building

antenna points toward the other.

Because the system uses radio

frequency to establish the connection

between the two buildings, it is

important to avoid blocking the radio

link with any objects, such as a trees,

buildings, walls, or items that are

attached to the building walls, such as stairwells,

fire escapes, or other antenna equipment.

Temporarily Connect the CPU

To use the IP ASSIGN Utility, you must first obtain a PC with a 10BaseT Network Interface Card that has its own

IP Address. The PC must not be running a DHCP Server while performing this procedure.

1. Determine the method that you are using to assign the IP Address:

Using a PC with a 10BaseT Network Interface Card: If you installed the IP ASSIGN Utility in a PC with a

10BaseT Network Interface Card, connect an RJ45, 10BaseT cable between the CPU and the jack on the

PC’s Network Interface Card.

Using the CPU Local Port: If you are using the local port, connect the serial port from a VT-100 terminal to

the CPU local port.

2. Connect the Radio Unit to the CPU.

3. Connect the CPU’s power adapter to the power jack on the CPU.

4. Plug the CPU’s power adapter into a 115VAC electrical outlet.

The CPU’s Power LED illuminates.

If you are using a PC with a network interface card, see Using the IP ASSIGN Utility to Assign the CPU’s IP

Address on page 14. If you are using the CPU local port, see Managing the CPU Locally on page 86.

Using the IP ASSIGN Utility to Assign the CPU’s IP Address

RadioLAN provides the IP ASSIGN Utility diskette with your package. The utility allows you

to assign an IP Address to the CPU quickly.

To install the IP ASSIGN Utility and assign an IP Address to the CPU, follow these steps

from a PC connected to the CPU:

1. Insert the IP ASSIGN Utility diskette into drive A.

2. Using the Windows RUN command, type A: IP ASSIGN and click OK.

The utility starts and begins searching the local LAN segment for any CPUs that are not

configured with an agent IP Address.

Figure 11:

Configuration

Disk

The utility returns a page listing of the Media Access Control (MAC) Addresses for all

non-configured CPUs on the LAN segment.

3. Highlight the MAC Address for the CPU that you want to configure.

4. Enter the desired temporary IP Address for the CPU. Later, you can permanently set it using the IP

PARAMETERS page.

The utility checks the IP Address to verify its validity. If the newly entered IP Address is valid, the utility

assigns it to the CPU and prompts you to configure the CPU using your network browser.

5. Choose Yes to launch your default network browser, and press Enter.

The utility displays the login page for the CPU configuration program.

Installing the CPU

When installing a CPU you must mount it onto a wall or a ceiling. You must locate the CPU at a distance from the

antenna that is no farther than the cable will allow. The cable length is a maximum of 15 feet; this means you

must consider all bends in the cable when determining your distance.

You must also locate the CPU in an area from which it has access to local network cabling and electricity. Before

selecting an electrical outlet for use in powering the CPU, verify that the electrical outlet is non-switched (for

example, it is not attached to a wall switch). You should also consider placing the CPU in a location where it is out

of reach of the general public.

FCC regulations require that this device be professionally installed by a person knowledgeable in

electronics and trained in the correct installation of this device.

All interface cables must be shielded.

Tools You Will Need

To install the CPU, you will need the following tools: drill, drill bit, screwdriver, screws, pencil, measuring tape.

Locating the CPU

After verifying that the

CPU is located near a

power source and network

cabling, and is within the

15-foot cable distance

constraint of the antenna,

you must install the CPU

securely to the mounting

surface (for example, a

wall or ceiling).

Mounting the CPU

When mounting the CPU, you must follow these steps.

Before mounting the CPU to the mounting surface,

connect the connector at the end of the CRM’s cable to

the 15 pin D connector on the CPU (see Figure 13).

Route the antenna cable from the directional antenna to

the CRM, and slip the cold-shrink tubing over the end of

the cable before connecting the cable to the antenna.

Connect the cable to the CRM, using a clockwise rotation.

Tighten the antenna connector so that it is snug but does

not strip the threads of the connector on the CRM.

Complete the shrink tubing installation by following the

instructions provided with the tubing.

Download from Www.Somanuals.com. All Manuals Search And Download.

Orient the CRM so that its cable does not cross over the mounting

brackets and then insert the CRM into the mounting bracket so that it is

flush with the rim of the bracket (see Figure 14).

Orient the CPU on the mounting surface in the location where you would

like it to be attached.

Figure 14: Inserting the CRM into the Bracket

890-007 Rev. A 01/28/99

Page 18

Download from Www.Somanuals.com. All Manuals Search And Download.

Use a pencil to mark the brackets screw hole locations onto the

surface upon which you will mount the CPU.

At the location’s screw holes, install any necessary anchoring

devices. This is especially recommended when installing the CPU

onto a sheet-rock or gypsum surface.

Hold the CPU up to the mounting surface (see Figure 15),

orienting the screw holes with the mounting anchors, then drive

screws securely into the surface. Tighten down the screws.

Connecting the Network

When connecting the CPU to the hardware network hub or to a

PC, you must use a RJ45-compatible, dual modular cable. The

cable is an eight-wire, twisted-pair cable and must not exceed the

distance limitations provided by the IEEE 802.3 standard. After

routing the cable to the network, insert the modular connector into

the port on the CPU.

Grounding Considerations

RadioLAN recommends that you properly ground the directional antenna as

described in mounting hardware installation instructions and required by

your local ordinances.

RadioLAN recommends that you connect the antenna assembly to a ground

rod driven a minimum of 10 feet into the soil. For proper grounding of the

antenna and cable follow Section 810 of the National Electrical Code. Use

UL-listed ground clamps and lugs.

Installing the Antenna

There are many methods for mounting the antenna onto

a wall. The assembly includes a U-bolt that allows you to

connect the directional antenna to a standard size

mounting assembly that is used for other directional

antenna applications. Directional antenna wall-mounting

assemblies are available at your local computer store or

retailer who sells directional antennas or satellite

services. The directional antenna uses a U-bolt with a

nut on each end. Slide the mounting clamp through the

two eyeholes on the backside of the directional antenna,

then secure the clamp to the mounting equipment that

you chose.

A Brief Word About Safety

If you chose to mount the antenna high up on a wall,

make sure that you use the appropriate type of ladder.

Follow ladder safety tips provided by its manufacturer. RadioLAN recommends that you have a partner available

to secure the ladder and to offer assistance while you are on the ladder. RadioLAN recommends that you not

mount the unit during stormy weather, on windy days, or anywhere near electrical cables.

Choosing the Best Mounting Height

Make sure that you choose the appropriate mounting height for the directional

antenna. You must consider the cable distance between the directional

antenna and the CPU, and the level of accessibility for routing cable and

mounting the CPU.

If the structure has an eave, RadioLAN recommends that you not place the

antenna up so high into the eave that the roof blocks a line-of-sight view to

the antenna on the distant Campus BridgeLINK™ building. Before securing

the antenna to the wall, verify that you can see the distant directional antenna

and that the line of site is clear of all obstructions.

Sighting Procedure

Campus BridgeLINK™ uses a 19° angle of reception for each of its antennas. This means that, from the center of

the directional antenna, you can angle away from your target for as much as 9.5° in any direction. This makes it

very easy to site the two antennas and align them properly.

Sighting greater distances: If your application requires that the buildings are nearly one mile apart, it may be

difficult to visually resolve the distant Campus BridgeLINK™ antenna. In these cases you may need a compass,

GPS, local maps, or other direction calibration equipment.

Greater distances increase probability for line-of-site blockages: As the distance between buildings

increases, there is a greater likelihood for objects appearing that block the line-of-site between Campus

BridgeLINK™ sites. When planning applications with greater distances, avoid problems caused by new

construction, or a large grove of trees between the two sites by placing the antenna higher. This decreases the

likelihood for line-of-site blockages through time.

Eyeball the Direction

Using a carpenter’s square (see Figure 19) align the square across the directional antenna’s surface and adjust

the antenna so that the carpenter’s square points toward the distant Campus BridgeLINK™ antenna location.

After aligning the antenna, tighten the nuts on the mounting assembly so that it stays affixed in this direction and

cannot be easily blown out of alignment by wind or heavy rain.

Next, connect the antenna cable to the back of the antenna. You can further align the two antennas, using the

Campus BridgeLINK™ Manager. See Aiming the Directional Antennas on page 33 for more information.

Adding Security to the Wireless Network

As an option, you can contact RadioLAN to enable the Data Encryption feature. This feature secures the wireless

link by setting an encryption key that protects your sensitive data on the wireless link. When you enable Data

Encryption, only CPUs that share the same encryption key can share data.

Local Management

The CPU includes a built-in serial port for connecting a VT-100 terminal or a modem. Using a terminal allows you

serial access configuration and system performance pages. Connecting a modem to the serial port allows you to

dial into the CPU from a remote location to log in and configure or view system performance.

Dual Remote Management: HTML and SNMP

The CPU contains an SNMP (Simple Network Management Protocol) agent. When a remote SNMP Manager

interrogates the agent, the agent presents system configuration and statistical information by way of the MIB

(Management Information Base). While connected to the agent through the network, the manager receives the

MIB and can see wireless network performance information.

When you use your SNMP Manager, you can make changes, see current status, and review new network history.

The CPU now supports SNMP management, using the standard MIB for selected functions. Contact RadioLAN

for a copy of the CPU’s MIB object functions.

The CPU’s interface includes system security authentication passwords, so only remote users with the correct

password can access and configure the CPU. The CPU offers up to three security access passwords, each

configurable for read and/or write rights.

System Requirements

To successfully place a CPU into operation, you must meet the following requirements:

The CPU must connect directly to a 10BaseT Network.

The CPU must be located within one mile of another Campus BridgeLINK™ CPU.

The network must use TCP/IP to communicate, using remote management.

Browser Requirements

To access the CPU by way of a 10BaseT Network, you must use a browser that is compatible with HTML, frames,

and Java™ script language, such as Netscape™ 4.x or Microsoft Internet Explorer™ 4.x provides.

Using the Campus BridgeLINK™ Manager

The Campus BridgeLINK™ Manager allows you to interrogate and interact with the CPU from a remote location

on the IP network, using a Web browser to communicate with the CPU. Your browser must support Java script

and frames. After launching your browser, enter the IP Address for the CPU. If you just set up the CPU for the first

time, you should have already assigned the CPU’s IP Address using the IP ASSIGN Utility or with the VT-100

terminal.

This section discusses how to find the CPU on your network, how to log onto the CPU, and how to use the CPU

Web Site.

The CPU Web Site

The Campus BridgeLINK™ Manager allows you to view pages which contain configuration information about the

CPU. Using the Web Site, you can assign passwords, set up IP Addresses for the CPU and SNMP management

stations, set address filters, and view system performance statistics.

When using the Campus BridgeLINK™ Manager to make changes, edit your choices on the site’s pages, then

accept all session changes by accessing the SYSTEM CONFIGURATION - CONFIGURATION CHANGES PAGE. This

causes the CPU to store configuration changes. Changes take effect after you save the changes and reset the

CPU (see Saving or Rejecting Configuration Setting Changes on page 77.

IP Address

The IP Address field allows you to designate the IP Address for the agent. The IP Address identifies the agent on a

TCP/IP Network.

The format of an IP Address is a 32-bit numeric address written as four numbers separated by periods. For

example, 223.142.15.200 could be an IP Address. The first segment ranges from 0 to 223, the last three

segments range from 0 to 255.

Within an isolated network, you can assign IP Addresses at random as long as each one is unique. If you are

connecting the CPU directly to the Internet, standards require using a registered IP Address to avoid duplicates.

Subnet Mask

The Subnet Mask field determines the subnet and IP Address for the agent. Typically, an IP Address contains the

network address and the host address.

If the network is divided into subnets, a part of the host address will be reserved to identify the particular subnet.

Default Gateway IP Address

The gateway is a combination of hardware and software that links two different types of networks. Gateways

between networks, for example, allow users on different e-mail systems to exchange messages.

The gateway IP Address might identify a router that controls the flow of data packets to the node (computer,

printer, etc.).

890-007 Rev. A 01/28/99

Page 40

Download from Www.Somanuals.com. All Manuals Search And Download.

Type in the gateway IP Address using four numbers, each separated by a period. The first segment ranges from 0

to 223, the last three segments range from 0 to 255. The address looks similar to the following: 221.040.123.243

DHCP Support

Short for Dynamic Host Configuration Protocol, this protocol assigns dynamic IP Addresses to devices on a

network. Dynamic addressing allows a device to have a different IP Address each time it connects to the network.

In some systems, the device's IP Address can change even while it is still connected.

Dynamic addressing makes network administration easier because the software tracks issued IP Addresses

rather than requiring an administrator to perform this task.

Disabled

The Disabled radio button disables DHCP support.

Bridging the Link and 10BaseT Networks

Because the CPU is a bridging device that connects a

10BaseT Network to a wireless link, the CPU must learn

about the network. The CPU dynamically learns MAC

Addresses as distant network nodes.

The CPU passes data packets that are addressed to far-end

network users found in its current service table. If a data

packet is addressed to a distant network node that is in the

current service table, the CPU accepts the data packet, then

forwards that packet to the distant CPU. When a distant node

is not in the current service table, the CPU does not pass

data packets for that node through to the wireless link.

This method of filtering keeps the wireless link free from

unnecessary messages, so that the wireless link provides the

maximum performance and speed possible.

Item

The Item column shows the order in which the CPU stored the database entry.

MAC Address

The MAC Address column displays the MAC Address (in six, two-character octets) for the remote network node.

Enter the MAC Address of the device that you want to enter into the database.

Although you can use 00 as a specific value for an octet, you can also use 00 when creating a “wildcard” octet.

Using wildcards allows you to specify a range of addresses, as opposed to just a single address.

For example, the first three octets of the MAC Address for all RadioLAN products is 00 A0 D4. If you want to allow

all RadioLAN products access to the CPU, set the MAC Address field to 00 A0 D4 00 00 00, and the Mask Bytes field to

ff ff ff 00 00 00. The wildcard is a result of a relationship between the MAC Address and the Mask Bytes field.

Mask Bytes

As an alternative to placing wildcards (00) in the MAC Address

field, the Mask Bytes column allows you to select which octets

in the MAC Address field will be read by the CPU (see

Figure 37).

Assigned to a Assigned by a

Manufacturer Manufacturer

Byte Position: 1

Entering ff into a mask bytes octet instructs the CPU to allow

only MAC octets with a value matching the same location in

the MAC Address field to pass. The CPU rejects any other

entry in the octet position.

MAC Address: 00 A0 D4 00 00 00

Mask Bytes: ff ff ff 00 00 00

ff = the byte in this position must match

00 = allow any digit in this section

Entering a 00 into a mask bytes octet instructs the CPU to

“mask” the octet. When the octet is masked, the CPU allows

any entry to pass.

Figure 37: Working with Mask Bytes

Entering an ff into a mask bytes octet, and a 00 in the same octet position of the MAC Address instructs the CPU

to allow an entry matching only 00 to pass.

Source/Dest.

The Source/Dest. column allows you to specify whether the action upon packets will occur if that node is sending or

receiving packets.

Accept/Reject

The Accept/Reject column permits you to allow or disallow transmission of the packet, depending upon the entry in

the Source/Dest. column.

For example, if Source is enabled in the Source/Dest. column, and the Reject radio button is enabled in the

Accept/Reject column, the CPU will not allow a message broadcast from that MAC Address to pass through. If

Destination is enabled in the Source/Dest. column, and the Reject radio button is enabled in the Accept column, the

CPU will not allow the message intended for that MAC Address to pass through.

Alternatively, if Source is enabled in the Source/Dest. column, and the Accept radio button is enabled in the

Accept/Reject column, the CPU allows the message from that MAC Address to pass through. If Destination is

enabled in the Source/Dest. column, and the Accept radio button is enabled in the Accept/Reject column, the CPU

allows the message from that MAC Address to pass through.

Adding MAC Filters

To add up to 32 MAC filters, select the first available (blank) Item:

1. Fill in the MAC Address and subnet Mask Bytes fields.

2. In the Source/Dest. column, select whether the filter will be invoked when the address is sending a packet or

when it is receiving a packet:

Choose Source if you want to filter messages that are broadcast from the MAC Address.

Choose Destination if you want to filter messages that are broadcast from other nodes and intended for receipt

by the MAC Address.

3. In the Accept/Reject column, you can allow or disallow the passage of the packet through the CPU based upon

the broadcast type (source or destination) in the Source/Dest. column:

Choose Accept to allow the passage of packets to/from the MAC Address.

Choose Reject to disallow the passage of packets to/from the MAC Address.

After adding all desired MAC Addresses, click the OK button to exit the EDIT page.

Spanning Tree Parameters

When you connect two or more networks to increase the

number of users, or enhance the ability for users of two (or

more) networks to communicate with one another, you can

control the routing of data to maximize the efficiency of the

traffic between the networks.

Network 1

Bridging characteristics allow you to route

necessary messages between two networks

Network 2

and to eliminate unnecessary traffic to other

networks when messages are only intended

for use within the local network.

Furthermore, you can set up redundant paths for bridging,

which reduces the potential for data path losses due to bridging

Network 3

network outages. You can establish a path redundancy for bridging

networks and redundancy for ports on the same

bridging network.

Figure 38: Bridging Networks

Path redundancy creates a loop by means of which data packets can potentially travel indefinitely if the bridge

root network were unable to dynamically “prune” pathways between each network. The SPANNING TREE

PARAMETERS PAGE allows you to set configuration items that allow the establishment of the root, redundancy of

root networks, redundancy of root network ports to other networks, and dynamic pruning between network loops.

The SYSTEM CONFIGURATION - SPANNING TREE

PARAMETERS PAGE allows you to set up bridging

characteristics for the CPU that conform to Spanning

Tree 802.1D protocol. The page displays the following

items:

Bridge Priority

Hello Time (1–10)

Forward Delay Time (4–3)

Max. Age Time (6–40)

Port Priority (0–255)

Port Path Cost (1–65,535)

Bridge Priority (0–65,535)

Each bridge has a unique bridge identifier. Priority is a

part of that identifier; it determines the topology.

Smaller priority entries increase the probability of the

network being selected as the root or primary bridge

between other networks.

Figure 39: Spanning Tree Parameters Page

890-007 Rev. A 01/28/99

Page 63

Download from Www.Somanuals.com. All Manuals Search And Download.

Hello Time (1–10)

Each time a network sends a frame, and no root bridge is present, the network sends a message that notifies

other networks of its request to be the root bridge. If no other network responds to this “Hello” message, the

network establishes itself as the root bridge between other connected networks.

When a network is established as being the root bridge, it sends the “Hello” message at the interval that you

select in the Hello Time field.

Enter a value between 1 and 10 seconds for the “Hello” message interval.

Forward Delay Time (4–30)

When a root bridge has redundant ports, it is necessary to set the secondary redundant port to forward

information only when the primary port has failed.

If the primary port operates normally, the bridge places the redundant port into a non-forwarding state, disallowing

communication of messages that were transmitted on the operating primary port. When the primary port fails, the

bridge places the redundant port into a forwarding state, which allows data packets to transmit to extended

networks where the message is intended.

Only the active root bridge uses this value. Any bridge not acting as the root bridge uses a dynamic value for

Forward Delay set by the root bridge.

890-007 Rev. A 01/28/99

Page 64

Download from Www.Somanuals.com. All Manuals Search And Download.

Enter the number of seconds (between 4 and 30) that the bridge will wait for the primary port to pass a frame

before switching the secondary port into the forwarding state, so that the secondary port can route data when the

primary port fails to do so.

Max. Age Time (6–40)

The bridge maintains a routing database, containing unique source addresses of frames that the bridge receives

from each network to which it is connected. The database relates a station’s source address to a port on the

bridge, and the bridge uses the database to choose which port it will use to transmit frames with a destination

address matching the entry in the database.

The bridge compares each new frame’s source address to entries within its internal routing database. If the bridge

does not find a new frame’s source address in the routing database, it adds the new frame’s source address to

the database.

The Max. Age Time field sets the amount of time in seconds that the bridge stores any source address. When the

bridge stores a frame’s source address, the address remains in the routing database for the length of time

specified in Max. Age Time. If the bridge receives a new frame, and finds the frame’s source address in the

database, the bridge automatically resets the Max. Age Time, restarting the count. If the aging timer for an entry in

the database expires before the bridge receives another frame with the same source address, the bridge removes

the source address from its internal routing database. This prevents the database from storing information about

inactive network stations.

Port Priority (0–255)

Bridges associate ports with physical devices, such as a router jack. A bridge can associate one or more ports

with a physical interface. Each port is associated with a port priority, which contributes the topology of the

network. The lower the number in this field, the higher the chance to become the designated port.

Port Path Cost (1–65,535)

Each port is associated with a port cost, which contributes the topology of the network. The lower the number in

this field, the higher chance to become the designated port.

Interrogating the System for Performance Information

Performance is a combination of speed and accuracy. When the CPU transmits at higher rates, and retransmits

packets fewer times, it has a higher rate of performance. Most users discover performance issues when sending

large files from one CPU to the other.

Although multiple users can send information across the link at the same time, lower shared network resources

can cause slower file transfer time. While data packets are being transferred, available link resources shared by

all users decrease, so when the CPU finishes the job faster, increased shared link resources are made available

for other packet transfers, making file transfer faster.

It is important to query the CPU for performance information occasionally. This allows you to determine when

performance issues arise over time and indicates where you can make changes to improve performance.

One change might require the adjustment of a directional antenna to improve signal strength. Another adjustment

might be filtering unnecessary packets to disallow passage into the wireless link. This type of fine-tuning is

intuitive and one can determine actions, based upon statistics found in the following pages.

Packet Transmission

The Packet Transmission section stores information about packets that are sent from the CPU to the distant

CPU.

Total Packets Transmitted

The Total Packets Transmitted field counts and stores the total number of packets that the CPU sends to the

distant CPU across the wireless link. This number represents all transmitted packets.

Average Transmit Rate (Packets/Sec.)

Sometimes packets are transmitted more rapidly than at other times. The maximum transmit rate for 64-

bit frames is approximately 14,600fps (frames per second). The Average Transmit Rate field indicates the

average number of packets sent each second. Typical networks range from 100 to 5000 frames

transmitted each second, and will vary with time. If you observe the rate consistently higher than

10,000 fps, you may have broadcast storms on your 10BaseT Network segment. These broadcast storms

can be caused, for example, by a defective Network Interface Card or too many IPX Network stations

sending broadcasts on the same network segment at the same time.

Total Retransmission

When the distant CPU does not acknowledge the receipt of a packet sent by the local CPU, the local

CPU resends the packet a number of times until the distant station acknowledges receipt of the packet.

The Total Retransmission field counts and stores the number of retransmissions, based upon the total

number of packets transmitted.

A higher number in this field may indicate the need to correct the alignment of a CPU’s directional

antenna. You may also need to remove objects that block the line-of-site of the two directional antennas

to improve signal quality.

Packet Reception

The Packet Reception section indicates the CPU’s ability to receive packets from the distant CPU.

Total Packets Received

The Total Packets Received field counts and stores the total number of packets that the remote CPU sends

to the local CPU. This number represents all received packets.

Average Receive Rate (Packets/Sec.)

Sometimes packets are received more rapidly than at other times. The Average Receive Rate field indicates

the numbers of average packets received each second. You should see approximately 100 – 5000 pps

(packets per second) under normal conditions.

Troubleshooting

This section discusses ways to eliminate trouble on the wireless link. We will provide cross-references to other

sections of the manual, which support corrective action.

The CPU bridges traffic between the wireless link and wired-backbone network. The unit provides several

indicators of its status and, with either a serial terminal or Web-based access, a user can use the tools built into

the CPU to further examine the network connection and help troubleshoot a problem report.

Indicators

In normal operation, verify that the power, 10BaseT, and radio connectors are attached. Verify that the Power

LED is illuminated, that the Status 1 LED is illuminated, and the Status 2 LED flickers when data is moving across

the link. If any of these do not operate as described, it may indicate a problem. For more information about

indicators, see LED Indicator on page 3. Contact your distributor for assistance. If you cannot reach your

distributor, or purchased the units directly from RadioLAN, contact RadioLAN Support.

Problem: No traffic for anyone

Using either the VT100, or Web management tools, check that the configuration is set correctly. Verify that the

filters are not set to block all traffic, or stop a specific protocol (see Bridging the Link and 10BaseT Networks on

page 49). Examine the statistic counters (see Interrogating the System for Performance Information on page 67),

and use the ANTENNA AIMING page (see Aiming the Directional Antennas on page 33) to “see” the quality of the

wireless link’s signal. Verify that the Subnet ID on each CPU is set to the same value. If using the Data Encryption

option, verify that both CPUs use the same encryption key, and that Data Encryption is enabled.

890-007 Rev. A 01/28/99

Problem: Radio Range seems less than it should be.

Check the placement of the directional antenna. Generally, the higher on the wall it is placed, the better the signal

pattern will be. If this link has been working for some time, inspect the antenna to see if it has been moved out of

alignment. Check the line of site between directional antennas to verify that no new construction or tree growth

has occurred, blocking the directional antenna link

If the problem persists and you have access to another CRM, try replacing the CRM. If this makes a difference, it

is possible the CRM may have become damaged, reducing its effectiveness. Contact your distributor for

assistance.

Problem: Retransmissions are excessive.

Verify that you selected and saved the correct Estimated Distance on the ANTENNA AIMING page (see Aiming the

Directional Antennas on page 33). This also sets internal CPU transmission timers. Using an incorrect setting can

cause retransmissions, which reduce the link’s efficiency and speed.

Glossary

Access Point

Agent

A service allowing wireless client stations to exchange data with an existing 10BaseT hard-

wired Ethernet Network.

Software at the device being controlled. The agent monitors the status of objects in an

information base called the MIB. The agent can be programmed to act on status changes and

send notification messages, called Traps, to designated IP Addresses called Trap

communities.

The agent can also take instructions from a remote manager to make changes to objects in

the MIB. For example, the manager might instruct the agent to change the system date and

time.

Client Station

A wireless 10Mbps computer that receives and originates Ethernet data. Client stations may

exchange data directly and/or send to other hard-wired network devices by using an access

point service.

DHCP Server

DNS

A protocol software that manages and tracks the assignment and use of static and dynamic

IP Addresses to devices attempting to connect to a network.

A system, which transfers a location’s alphanumeric URL address into the site’s

corresponding numerical IP Address.

Domain

A grouping of devices that are members of a specific realm or location on a network. Each

device is identified on the Internet by a specific extension attached to the location’s IP

Address which is shared among all devices within the domain.

Gateway

A doorway to the Internet that allows a member of one domain access another domain. (The

domains have different IP Addresses.)

IP Address

Internet Protocol Address. Numerically based address of Internet sites. It is composed of four

numbers that are linked by a period. The first segment ranges from 0 to 223, the last three

segments range from 0 to 255. For example, 222.8.44.155. The numbers in the address

indicate the domain of the site and the user of that site. Such an address can be assigned by

a private network administrator for a private network but, for use on a larger scale, one

should obtain an address from the InterNIC Registration Service which assigns a different

address to each user.

MAC Address

Media Access Control Address. Basic numerical address used to identify all types of nodes

on networks based on the IEEE 802 standards. Protocols may assign to nodes different

addresses that coincide with their system. Ultimately, however, that address can be traced to

the node’s MAC Address. This address is also referred to as a Data Link Control address by

OSI Reference-based networks.

Manager

Software used to control and manipulate the Management Information Bases (MIB) through

communication with the agent.

890-007 Rev. A 01/28/99

Page 111

Download from Www.Somanuals.com. All Manuals Search And Download.

MIB

Management Information Base. A database of information about a particular community

within a network including information about the activities of that community. This information

can be reviewed for understanding of activities of the MIB and troubleshooting.

Node

Any device connected to a network. It is assigned either a MAC Address (IEEE 802 Standard

network) or a DLC Address (OSI Reference network).

Packets

PING

A portion of a file being sent over the Internet. The portion contains part of the original file and

the destination IP Address for the document.

Packet Internet Groper. A program used for verifying/testing network connectivity between

two or more computers by transmitting a special diagnostic packet to those stations on the

network. It forces the receiving station to send a reply indicating that the packet reached its

destination. It obtains information about the connection, by determining the amount of time for

packet delivery and station response.

Routing

The path chosen by the user over which to send a packet of information from one computer

or station to another via the network.

Subnet Mask

TCP/IP

A network address that numerically represents the IP Address, including the network address

and the subnet of which the IP Address is a member.

Transport Control Protocol/Internet Protocol. The combination of protocols that are used on

the Internet to transfer data from one address to another.

Appendix A: Indicators, Switches, and Connectors

Indicators

10BaseT Port LEDs

There are two built-in LEDs located on the 10BaseT connector which provide link and port activity information.

The CAR LED (green) is active when the port is connected to another powered 10BaseT port whose signaling

meets the requirements for an IEEE 802.3i 10BaseT device (for example, valid link test pulses are detected

on the receive pair).

The ACT LED (green) is active when receive activity is detected or during a packet transmission.

Power LED

The Power LED (green) is active when power is provided to the unit.

Fault LED

The fault LED (amber) is active when a fault is detected during power up diagnostics.

Status LEDs

The green Status 1 LED illuminates when the CPU detects the presence of the distant CPU. When the CPU is

operating, this LED normally illuminates when the near and far CPUs are active.

The green Status 2 LED illuminates when the CPU detects the presence of data passing through the wireless link.

During normal CPU operation, this LED flickers when near and far CPUs are active.

MDI/MDI-X Switch

Interconnection on a 10BaseT Network must always be between MDI to MDI-X. The transmitter of each device

must connect to the receiver of the other device. The reversal of the transmitter and receive assignments is called

a crossover function. Every 10BaseT interconnection requires a crossover function. Generally, 10BaseT ports

on an adapter card are configured as MDI, and 10BaseT ports on a repeater/hub are configured as MDI-X.

The CPU allows you to configure its 10BaseT port as an MDI (switch out position) or MDI-X (switch in position)

port. The abbreviation MDI stands for Media Dependent Interface, and is specified by the IEEE 802.3i 10BaseT

standard to be the electrical and mechanical interface to the UTP wire. An MDI port transmits out to the UTP wire

on pins 1 and 2, and receives from the UTP wire on RJ-45 pins 3 and 6.

The MDI/MDI-X switch swaps the pin assignments of transmit and receive data wire pairs for the 10BaseT port.

MDI-X configuration is used when the remote end of the wire is connected to a network station (for example,

a10BaseT adapter card) or to an MDI port on a 10BaseT concentrator. MDI configuration is used when the

remote end of the wire is connected to a 10BaseT concentrator.
